ai-sdk-provider-dsh

Install

npm install ai-sdk-provider-dsh

The dsh runtime is bundled: the package ships a default runtime composition (runtime/cordis.yml) plus the dsh-jsonrpc-agent bin (via @deepseek-ai/dsh-sdk-jsonrpc-demo), and all runtime plugins are pinned exact versions in dependencies. A provider instance spawns a working runtime out of the box — no separate install.

Credentials come from the runtime's environment:

export DEEPSEEK_API_KEY=sk-...                                        # required
export DEEPSEEK_BASE_URL=https://api.deepseek.com                     # optional; any OpenAI-compatible gateway works

Quick Start

streamText (AI SDK v7)

import { streamText } from "ai";
import { createDsh } from "ai-sdk-provider-dsh";

const dsh = createDsh({
  runtime: { provider: "deepseek-official", model: "deepseek-v4-flash" },
});

const result = streamText({
  model: dsh.languageModel("deepseek-v4-flash"),
  instructions: "You are a coding agent.",
  prompt: "run the tests",
});

const text = await result.text;
console.log(text);

streamText (AI SDK v6)

import { streamText } from "ai";
import { createDsh } from "ai-sdk-provider-dsh";

const dsh = createDsh({ runtime: { provider: "deepseek-official", model: "deepseek-v4-flash" } });

const result = streamText({
  model: dsh.languageModel("deepseek-v4-flash"),
  system: "You are a coding agent.", // v6 name; v7 uses `instructions`
  prompt: "run the tests",
});

generateText

import { generateText } from "ai";
import { createDsh } from "ai-sdk-provider-dsh";

const dsh = createDsh({ runtime: { provider: "deepseek-official", model: "deepseek-v4-flash" } });
const { text } = await generateText({
  model: dsh.languageModel("deepseek-v4-flash"),
  prompt: "say hello",
});

Provider factory

const dsh = createDsh(options);        // returns the provider
dsh.languageModel("deepseek-v4-flash") // the LanguageModel
dsh("deepseek-v4-flash")               // callable alias (AI SDK provider convention)
await dsh.close();                     // tear down the runtime subprocess (idempotent)
